摘要:
Chiral, ionic C-2-symmetric binaphthyl fluorophores with amphipathic "property can emit circularly polarized luminescence (CPL) in the near-UV region when dissolved in either water or methanol. Despite the same axial chirality (R or S) of the binaphthyl units, the open- and closed-style fluorophores induced sign inversion of CPL and circular dichroism (CD) signals in water. The dihedral angle of the binaphthyl C-2-axis appears to determine the signs of CPL and CD signals even in water. (C) 2017 Elsevier Ltd. All rights reserved.
